2) No matter how hard a diamond is, wisdom can make it soft.
3) For the blind, pebbles are no different from diamonds.
4) Diamonds will never rot.
5) The results show that the repair and regeneration layers of friction surface are diamond-like carbon film and Shi Ying glass film.
6) Polycrystalline diamond is a new tool material with high hardness and wear resistance, which is widely used in industrial fields.
7) Product features: The raw material is high-quality diamond with high strength and purity, which is processed by special crushing and shaping processes, and the crystal form is regular polygonal particles with nearly equal area.
8) The calibrated diamond film dosimeter can be used for quantitative detection of radiation dose.
9) On the basis of theoretical analysis, the experimental study of laser cutting and polishing diamond films was carried out.
10) were used to measure the secretion levels of nitric oxide and prostacyclin in human umbilical vein endothelial cells (HUVECs) and blank control group, and the activity was evaluated by lishixinzhi/963883 1.
1 1) A rare agate-like growth structure in Mengyin diamond was discovered for the first time by this technique, and the characteristics and growth mechanism of this typical structure were analyzed.
12) So diamonds became the favorite thing of kings and queens in Europe.
13) The main products are diamond saw blades.
Soft grinding disc and other diamond tools.
14) and the study of colloidal chemical properties of nano-diamond is the basis of practical application.
15) Based on the uniform distribution of diamond in impregnated drill bit, the depth and stress of diamond at different radial positions on the lip surface are theoretically deduced.
16) determines the overall scheme of diamond wire saw which can cut the oil pipeline of submarine dry warehouse, and designs and calculates the main components.
However, pure iron is rarer than gold or diamonds.
18) rough machining can be carried out with diamond grinding disc, ceramic rubber grinding disc and sandpaper grinding disc.
19) abstract: diamond bit: suitable for bench drill, imported and domestic mechanical special equipment.
20) The cutting performance of synthetic diamond tools for processing nonferrous metals is studied experimentally.
2 1) found that only four areas have more diamond reserves.
22) Study the changing law of cutting force and cutting temperature when diamond tools cut silicon-aluminum alloy.
23) Using pyrophyllite from Qingtian Mountain Pass as pressure transmission medium, diamond was synthesized at ultra-high pressure and high temperature, and its main chemical and mineral components were analyzed.
24) The former is made of ordinary abrasives such as corundum and silicon carbide, and the latter is made of superhard abrasives such as diamond and cubic boron nitride.
25) Suitable for consumables that need to provide torque, such as diamond drill, spindle grinding wheel, rubber polishing wheel brush, etc.
26) During the maintenance of submarine oil and gas pipelines, according to the submarine working conditions and the special structure of oil and gas pipelines, underwater diamond wire saw is used to cut the pipelines.
